Composite Core Speeds Construction

摘要

Cast-in-place reinforced-concrete cores have been the structural system of choice in high-rise construction for decades. However, that could now change: Practitioners and researchers have worked together to design and test a concrete-filled, composite steel-plate shear wall core system based on technology previously used for blast and impact protection in the defense and nuclear industries. The nonproprietary system - dubbed SpeedCore - has already been written into the ASCE 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures standard and will be included in the American Institute of Steel Constructions 341-22 Seismic Provisions for Structural Steel Buildings standard.
